gh-104745: Limit starting a patcher more than once without stopping it (GH-126649)
Previously, this would cause an `AttributeError` if the patch stopped more than once after this, and would also disrupt the original patched object.

gh-119600: mock: do not access attributes of original when new_callable is set (GH-119601)
In order to patch flask.g e.g. as in GH-84982, that
proxies getattr must not be invoked. For that,
mock must not try to read from the original
object. In some cases that is unavoidable, e.g.
when doing autospec. However, patch("flask.g",
new_callable=MagicMock) should be entirely safe.

Add tests for "import", pkgutil.resolve_name() and unittest.mock.path()
for cases when "import a.b as x" and "from a import b as x" give
different results.

autospec=True.
